In June, the Bollingstedt Energy Storage Station in Germany officially went online, becoming the country’s largest energy storage project to date. Covering an area of 1.2 hectares, it boasts an installed capacity of 103.5 MW and an energy storage capacity of 238 MWh, equivalent to providing green electricity to 170,000 households for two consecutive hours.
Project Overview
The energy storage station utilizes 64 sets of BYD’s MC Cube BESS Magic Cube energy storage systems. Key technical features include:
- Super-integrated design: Batteries are directly integrated into the storage units, achieving a space utilization rate of 98% and a cell-to-system volume ratio (Vcts) of over 33%. This maximizes energy storage capacity per unit area. During project construction, this design effectively reduced land occupation and infrastructure costs while shortening the overall construction period by approximately 15%.
- Blade Battery technology: It passes rigorous tests such as nail penetration, ensuring excellent thermal runaway protection. A modular compartmentalized design isolates batteries, electrical components, and firefighting modules independently. Coupled with a liquid cooling temperature control system, it ensures stable battery operation under various environmental conditions.
- Equipped with a management platform: The system can monitor battery status, charging/discharging power, and temperature in real time. It supports fault prediction and data analysis, optimizing charging/discharging strategies to enhance operational efficiency and reduce maintenance risks.
